View with Virtual Folder hierarchy (Property Folder - Grouping Levels)

Hello everyone,

Our customer needed a specific report for a document type, the objective was to calculate the total weight of each project (the weight was mentioned in the document properties).

So we have a View (Document : by project), the grouping level is done with the Project Lookup, so you have then one Virtual Folder for each existing Project. My goal was to look for each document in each virtual folder with the COM API (using Powershell).

The big problem I had, was to succeed in getting the items (ObjectVersion) from each virtual folder (which are the projects). When I set the PropertyFolder and tried to get its content, I had an “Invalid Search Condition” error

Hope it can help somebody out there, the point is to:

Create a FolderDefs AND a FolderDef set with the View ID
Get the FolderContents with these objects
Create a second FolderDefs AND a FolderDef set with the property folders
Add FIRST the FolderDef (View) and SECONDLY the FolderDef (PropertyFolder) in the second FolderDefs collection you've just created (The positions are very important)
Get the FolderContents with these second objects
Retrieve your ObjectVersion

P.S. I know the code might be very dirty (but don't have the time to polish it)
